Cannot check checkbox - Thymeleaf - html

Question

I have a list of users in a table with a column at the end that has checkboxes so if a user clicks on any of the checkboxes, he can delete the user in that row.
However, after I added the th:field="*{checkedUsers}" tag, I am not able to click any of the check boxes.
Here is the HTML code for that:

Any ideas?
Thanks
EDIT:
I realize it could be something to do with the <label> tag:
The tag defines a label for an <input> element.
The <label> element does not render as anything special for the user.
However, it provides a usability improvement for mouse users, because
if the user clicks on the text within the <label> element, it toggles
the control.
The for attribute of the <label> tag should be equal to the id
attribute of the related element to bind them together.

Is this the problem? And if so, how could I work around it?
EDIT 2:
<label> had nothing to do with it. I replaced it with <span> and I still can't click on any of the check boxes.
EDIT 3:
The th:field="*{checkedUsers}" field is an ArrayList of User objects that are checked and would populate the form-backing bean DeleteUsersForm
Here is that bean class:
public class DeleteUsersForm {
private List<User> checkedUsers;
public DeleteUsersForm() {
}
public DeleteUsersForm(List<User> checkedUsers) {
this.checkedUsers = checkedUsers;
}
public void setCheckedUsers(List<User> checkedUsers) {
this.checkedUsers = checkedUsers;
}
public List<User> getCheckedUsers() {
return checkedUsers;
}
}

Just realized it was the CSS that was preventing it this whole time. I am using topcoat.
